What is an AI App Builder?

Create an actual AI app

An AI app builder lets you create mobile applications with built-in AI chat powered by leading language models. Swiftspeed is the most powerful AI mobile app builder on the market, letting you embed a fully customizable AI assistant directly into your native app.

Connect your own API key from Anthropic (Claude), OpenAI (GPT), or xAI (Grok), train the AI with custom system instructions, brand it with your own name and avatar, and publish to both app stores. Your users get real-time streaming responses, markdown rendering, code highlighting, and a beautiful chat experience.

How It Works

Generate an AI app in four steps

No machine learning expertise. No backend infrastructure. The Swiftspeed AI app builder handles the entire process from API connection to app store submission.

1

Connect your AI provider

Add your API key from Anthropic, OpenAI, or xAI. The AI app builder validates the key and fetches available models automatically.

2

Train and brand your AI

Write system instructions to define your AI's behavior. Set a custom name, avatar, welcome message, and suggested prompts for your users.

3

Pick a theme and layout

Choose from 6 chat themes (Aurora, Daylight, Midnight, Sunset, Forest, Minimal) and 3 layouts (Classic, Immersive, Sidebar). Override any color.

4

Publish to app stores

Build your native app and publish to Google Play and the App Store. Your AI assistant is embedded directly in the app, ready for your users.
